Description

  The present invention relates to an ice making device (mobile ice making device having a high degree of freedom of installation location) that generates ice with high transparency rapidly and efficiently and that does not select an installation location.

  When an ice making device tries to generate a large amount of ice, it requires a large amount of ice making water as a source of ice. In addition, in order to increase the transparency of this large amount of ice, it is necessary to adopt an ice making method suitable for producing highly transparent ice.

  For example, as a means for an ice making apparatus to secure a large amount of ice making water, there is a means for directly connecting a water pipe or the like through which tap water flows. When this means is used, tap water can be utilized as ice making water, so that a large amount of water can be secured.

  Moreover, as one means for generating ice with high transparency, there are ice making methods such as Patent Document 1 and Patent Document 2. In these systems, gas components (impurities) such as air dissolved in water are diffused without being trapped in the ice as fine bubbles, so that cloudy ice is not generated.

Specifically, the ice making device 189 of Patent Document 1 shown in FIG. 8 diffuses impurities in the ice making water by flowing down the water stored in the ice making water storage tank 101 onto the ice making plate 125a. Water is iced on the ice making plate 125a. Further, the ice making device 189 of Patent Document 2 shown in FIG. 9 diffuses impurities in the ice making water by blowing the ice making water from the supply pipe 121 to the ice making tray 125b including the ice making block. Pure water is iced in the ice making block of the ice tray 125b.
Japanese Patent Laid-Open No. 11-142033 (see FIG. 3) Japanese Patent Laying-Open No. 2003-222451 (see FIG. 1)

  Such ice making apparatuses 189 and 189 disclosed in Patent Documents 1 and 2 can surely quickly produce transparent ice. However, when a large amount of ice is to be generated, the water pipe or the like and the ice making water storage tank 101 or the like must be connected as described above.

  In addition, when trying to generate ice with higher transparency, the ice freezing water dripping from the ice making plate 125a and the ice making plate 125b is not circulated permanently [the ice making water storage tank 101 and the ice making plate 125a ( It is preferable that the water is drained at regular intervals rather than permanently circulating between the ice tray 125b) and the like.

  Then, an ice making device for generating a large amount of highly transparent ice can obtain a large amount of water by connecting it with, for example, a water pipe, etc. The water must be drained. Therefore, such an ice making device is connected to a drain pipe or the like.

  The ice making device capable of making a large amount of highly transparent ice connected to a water pipe or a drain pipe as described above has a problem that the installation place is limited. That is, the problem that an ice making apparatus can be installed only in the position which can be connected with a water pipe etc., a drain pipe, etc. will arise.

  Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide an ice making device in which the restriction of the installation location is reduced.

  The present invention relates to a first ice-making water storage unit that stores water blown against a cooled ice-making unit, and one end and the other end of the first ice-making water storage unit connected to each other to store the stored water. The flow path for circulating the water and the water stored in the first ice making water storage section are blown to the ice making section, and the water flowing down from the ice making section is passed through the circulation path to the first ice making section. A mobile ice making device including a pump unit that circulates to a water storage unit, and is characterized in that an independent storage unit capable of storing water is provided.

  In particular, the storage unit may be a second ice-making water storage unit configured to store water supplied to the first ice-making water storage unit, or water stored in the first ice-making water storage unit. When the wastewater becomes drainage, it may be a drainage water storage unit configured to store the wastewater.

  The mobile ice making device is different from an ice making device that is not premised on a long-term movement in a home kitchen, a pantry of a restaurant / hotel, or the like. That is, the mobile ice making device is a type of ice making device that can be easily moved to a banquet hall such as a hotel and used during the banquet, but can be moved to another place for storage after the banquet.

  Such a mobile ice making device is preferably provided with a leg ring or the like to ensure ease of movement.

  For example, although there is a facility for easily supplying water using a water pipe or the like, in an environment where it is difficult to drain water using a drain pipe or the like, the ice making device of the present invention can While attaching a water storage part with respect to an ice making apparatus, tap water can also be utilized as ice making water, for example via a water supply port, without providing a 2nd ice-making water storage part. That is, even in a place where there is no drain pipe or the like, the ice making device of the present invention can be moved and installed and used.

  In addition, when it is desired to use purified water to improve the quality of ice, but the quality of the drainage itself is not concerned, the ice making device of the present invention can make only the second ice making water reservoir. While being attached to the apparatus, it is possible to dispose of unfrozen water or the like into a drain pipe, for example, through a drain port or the like without providing a drainage reservoir. That is, even in a place where a water pipe or the like does not exist, the ice making device of the present invention can be moved and installed and used. Therefore, the ice making device of the present invention can reduce the restriction of the installation location.

  An embodiment of the present invention will be described below with reference to the drawings.

<About ice making and de-icing detection sensors>
The ice making / deicing detection sensor 51 is a sensor that determines whether or not ice is formed in the ice tray 25 and determines whether or not the ice generated from the ice tray 25 is deiced. The temperature of the dish 25 is measured. That is, for example, a temperature sensor can be considered as the ice making / icing detection sensor 51.

  Specifically, in the case of a temperature sensor, a threshold temperature (ice making completion threshold temperature) for determining completion of ice making stored in a control unit 71 (to be described later) and a threshold temperature (ice removal completion threshold for determining completion of ice removal) are stored. Temperature) and the detected temperature of the ice tray 25 are determined.

  That is, when determining the completion of ice making, it is determined whether the temperature of the ice tray 25 is higher or lower than the ice making completion threshold temperature (a certain temperature at approximately −15 to −20 ° C.). This is because if the ice tray 25 cooled by the cold gas cycle is lower than the ice making completion threshold temperature, it can be determined that the ice making water has completely grown into ice.

  On the other hand, when the completion of deicing is determined, it is determined whether the temperature of the ice tray 25 is higher or lower than the deicing completion threshold temperature (a temperature exceeding the freezing point (0 ° C.)). This is because, if the ice tray 25 heated by the hot gas cycle is higher than the deicing completion threshold temperature, it can be determined that the ice surface has melted and that the ice tray 25 and the ice are not fixed.

《About ice making water storage detection sensor》
The ice-making water storage amount detection sensor 52 determines whether the ice-making water storage tank 1 is attached to a predetermined position of the ice making device 89 (whether it is set) or ice-making water stored in the ice-making water storage tank 1. This is a sensor that detects whether or not the amount of ice (the amount of ice-making water stored) is sufficient. As this ice-making water storage amount detection sensor 52, a weight sensor, a water level sensor, etc. can be considered, for example.

  Specifically, in the case of a weight sensor, by detecting the weight of the ice-making water storage tank 1, the weight (threshold ice-making water weight) stored in advance in the control unit 71 and the detected weight are determined. The control part 71 compares. In other words, in the case of a weight sensor, whether the detected weight (detected water storage amount) is heavier or lighter than the threshold ice making water weight (threshold water storage amount; threshold weight water storage amount), the ice making water storage amount or ice making water storage tank 1 The presence or absence of a set is determined.

  Further, in the case of a water level sensor, a float (floating) (not shown) is floated on the ice-making water storage tank 1, and the position of this float is detected (for example, by detecting the position of the float magnetically). The amount of storage is determined.

《About waste water storage amount detection sensor》
The drainage water storage amount detection sensor 53 is a sensor that detects the amount of wastewater stored in the drainage water storage tank 2 (amount of uniced water or the like). For example, use of a weight sensor as described above can be considered.

  For example, in the case of a weight sensor, the control unit 71 compares the weight (threshold drainage weight) determined in advance and stored in the control unit 71 with the detected weight by detecting the weight of the drainage storage tank 2. It is supposed to be. That is, in the case of a weight sensor, the amount of stored wastewater is determined based on whether the detected weight is heavier or lighter than the threshold drainage weight (threshold drainage amount; threshold weight drainage amount).

  Further, the drainage / water storage amount detection sensor 53 including such a weight sensor may be configured such that the control unit 71 compares the detected weight with the drainage / water storage tank threshold weight with the weight of the drainage water storage tank 2 as a threshold. It has become. In other words, the drainage / water storage detection sensor 53 sets the drainage / storage tank 2 depending on whether the detected weight (detected wastewater amount) is heavier or lighter than the drainage water tank threshold weight previously determined and stored in the control unit 71. Judgment of the presence or absence of.

About the temperature sensor in the ice storage
The ice storage temperature detection sensor 54 is a sensor (for example, a temperature sensor) that detects the temperature (atmosphere temperature) in the ice storage 27, and the amount of ice stored in the ice storage 27 (ice storage amount), For example, it is a sensor that detects whether or not ice is present in the ice storage 27 and whether or not the allowable storage amount in the ice storage 27 is exceeded.

  Specifically, in the case of a temperature sensor, by detecting the temperature of the ice storage 27, the temperature (threshold temperature; for example, 5 ° C.) that is predetermined and stored in the control unit 71 and the detected temperature are: The control part 71 compares. That is, in the case of a temperature sensor, the ice storage amount is determined based on whether the detected temperature is higher or lower than the threshold temperature.

  That is, in the ice storage 27 composed of a heat insulating material, when ice is present, it is around the freezing point (about 0 ° C.), and when there is no ice, it is at room temperature (about 25 ° C.). Therefore, in the case of a temperature sensor, the control unit 71 detects the amount of ice stored by detecting the temperature in the ice storage 27 by installing it on the side surface in the ice storage 27 (whether or not there is ice). And how much ice is stored).

<About the ice storage amount detection sensor in the ice storage>
The ice storage amount detection sensor 55 in the ice storage is similar to the above (similar to the temperature detection sensor 54 in the ice storage), and the amount of ice stored in the ice storage 27 (ice storage amount), for example, whether ice is present in the ice storage 27 or not. This is a sensor for detecting whether or not the allowable storage amount in the ice storage 27 is exceeded. As the ice storage amount detection sensor 55 in the ice storage, a weight sensor or the like can be considered.

  Specifically, in the case of a weight sensor, the weight stored in the control unit 71 (threshold ice storage weight) and the detected weight are detected by detecting the weight of the ice storage 27 and the control unit 71. Have come to compare. That is, in the case of the weight sensor, the ice storage amount is determined based on whether the detected weight (detected ice storage amount) is heavier or lighter than the threshold ice storage weight (threshold ice storage amount; threshold weight ice storage amount).

<About the ice-making water set timing sensor>
The ice making water set timing discrimination sensor 56 has a timer function, for example, and determines ON / OFF of a buzzer (notification sensor) 61 attached to the ice making device 89.

  This ice making water set timing discrimination sensor 56 measures the passage of a certain time (threshold elapsed time; this threshold elapsed time is stored in the control unit 71) with the timer function since the ice making water is added. Then, after the threshold time has elapsed (when the measurement elapsed time is longer than the threshold elapsed time), the buzzer 61 transmits a signal necessary for generating a notification sound to the control unit 71. Therefore, the user can recognize the timing for setting the ice making water (the timing for replacing the ice making water) by the notification sound.

<1-6. Control section>
The control unit 71 controls the operation of various drive sources. For example, as shown in the block diagram of FIG. 3, driving based on the detection result of the sensor group described above, driving (starting) of the refrigeration cycle unit 19, driving of the pump 23, and a valve mechanism that is a power source of the valve mechanism of the three-way valve Control of driving of the driving motor 22z for the shaft, driving of the driving motor 24z for the shaft, which is a power source of the rotating shaft 24a for rotating the circulation tank 24, and the like are performed.

[2. About ice production process by ice making equipment)
Here, the ice production process of the ice making device 89 of the present invention will be described with reference to the block diagram of FIG. 3 and the flowchart of FIG. In this flowchart, the operation step is described as S for convenience.

  First, the ice making water storage tank 1 storing necessary ice making water is attached to a predetermined position of the ice making device 89, and the waste water storage tank 2 not storing waste water is attached to a predetermined position of the ice making device 89 (S1).

  Then, for example, in the case of the ice-making water storage amount detection sensor 52 composed of a weight sensor, the control unit 71 determines that the weight detected by the ice-making water storage amount detection sensor 52 is heavier than the threshold ice-making water weight. It is determined that 1 is set (YES in S2).

  Further, in the case of the wastewater storage amount detection sensor 53 using a weight sensor or the like, the control unit 71 detects the wastewater storage tank 2 when the weight detected by the wastewater storage amount detection sensor 53 is heavier than the drainage storage tank threshold weight. Is set (YES in S3).

  When recognizing completion of setting of the ice making water storage tank 1 and the drainage water storage tank 2, the control unit 71 transmits a signal to the effect that a cold gas cycle is performed to the refrigeration cycle unit 19 (S4). At almost the same time, the control unit 71 transmits a signal for driving the valve mechanism drive motor 22z, which is the power source of the valve mechanism of the three-way valve 22, to cause the water absorption pipe 21a and the fountain pipe 21b to communicate with each other. (S5).

  In this way, when the water absorption pipe 21a and the fountain pipe 21b communicate with each other, the ice making water in the ice making water storage tank 1 is led to the circulation tank 24. Therefore, the control unit 71 transmits a signal to the pump 23 to pump up a predetermined amount of ice making water.

  Thereafter, if it can be determined that a certain amount of ice-making water has been supplied to the circulation tank 24, the control unit 71 transmits a signal for driving the valve mechanism drive motor 22z to connect the circulation pipe 21c and the fountain pipe 21b. (S6).

  Then, a circulation route of “circulation tank 24 → ice tray 25 → circulation pipe 21c → three-way valve 22 → fountain pipe 21b → circulation tank 24” is established. That is, while the ice making water attached (arrives) to the ice tray 25 becomes ice, the ice making water that has not adhered becomes unfreezing water, and a state is established in which the ice making water is sprayed again to the ice tray 25 through the circulation route. .

  Therefore, the control unit 71 transmits a drive signal to the pump 23, and uses the discharge force of the pump 23 to spray the ice making water in the circulation tank 24 onto the ice making tray 25 (S7).

  In this way, the ice making water is sprayed onto the ice making tray 25, and when a certain time has elapsed, the control unit 71 determines whether or not the detection temperature of the ice making / icing detection sensor 51 is lower than the ice making completion threshold temperature. to decide. When the detected temperature is lower than the ice making completion threshold temperature, the control unit 71 determines that ice has been generated in the ice tray 25 (YES in S8).

  However, when ice is not yet generated in the ice tray 25, that is, when the detection temperature of the ice making / icing detection sensor 51 is higher than the ice making completion threshold temperature, the controller 71 continues to circulate. The pump 23 is driven in a state where the pipe 21c and the fountain pipe 21b are in communication (S8 → S6 → S7).

  Then, the non-iced water stored in the circulation tank 24 is again sprayed to the ice tray 25 through the circulation pipe 21c and the fountain pipe 21b. That is, the ice-making water pumped from the ice-making water storage tank 1 can be used again even if it becomes unfrozen water.

  On the other hand, as described above, when the control unit 71 determines in S8 that the detection temperature of the ice making / icing detection sensor 51 is lower than the ice making completion threshold temperature (that is, ice has already been generated in the ice making tray 25). When it is determined that the circulation tank 24 is separated from the ice tray 25 (that is, a signal for performing forward driving) is transmitted to the shaft drive motor 24z (S9).

  Then, the circulation tank 24 rotates in the direction to turn over and drops unfrozen water. Therefore, the unfrozen water that falls (flows down) passes through the net portion 26 a of the cushion tank 26 and reaches the cushion tank 26. Then, the reached uniced water flows through the C drain pipe 31 to the drain water storage tank 2.

  Further, the control unit 71 transmits a signal for separating the circulation tank 24 from the ice tray 25 to the shaft drive motor 24z, and at the same time, performs a hot gas cycle to the refrigeration cycle unit 19. A signal indicating that this is to be performed is transmitted (S10).

  Then, the evaporator 15 is heated by the hot gas, and the surface of the ice fixed to the ice tray 25 is melted. As a result, the ice falls from the ice tray 25 toward the cushion tank 26 (ice removal). It becomes like this. The deiced ice rolls on the net portion 26a of the cushion tank 26, reaches the ice storage 27, and is stored.

  In addition, after the hot gas cycle, the melted water (dissolved water) on the ice surface passes through the net part 26a of the cushion tank 26 and then flows to the drainage water storage tank 2 through the C drain pipe 31. Yes.

  Next, when the control unit 71 determines that the detection temperature of the ice making / icing detection sensor 51 is higher than the deicing completion threshold temperature (that is, the ice surface is melted in the ice tray 25 and the sticking is released). If it is determined), a signal for bringing the circulation tank 24 into close contact with the ice tray 25 (that is, a signal for performing reverse driving) is transmitted to the shaft drive motor 24z (S11). Then, the circulation tank 24 comes into close contact with the ice tray 25 (that is, a position where ice-making water from the circulation tank 24 can be received), and the ice-making device 89 becomes ready for ice-making again.

  In addition, the process from S1 to S8 in the above description is expressed as an ice making process, and the process from S9 to S11 is expressed as an ice removal process. Further, when the generation of ice is continued (when the ice making process and the deicing process are repeated), the process returns to the step to S5 (NO in S12).

[3. Various features of the ice making device of the present invention]
As described above, the ice making device 89 of the present invention includes the circulation tank 24 that stores the ice making water blown against the ice tray 25 that has been cooled. The fountain pipe 21b and the other end of the circulation tank 24 are provided at one end. The circulation pipe 21c is connected to the two and the two (fountain pipe 21b and circulation pipe 21c) are connected via the three-way valve 22 so as to form a circulation flow path serving as a flow path for circulating ice-making water. It has become.

  Further, the ice-making water stored in the circulation tank 24 is blown to the ice-making tray 25, and the ice-making water (unfreezing water) flowing down from the ice-making tray 25 is supplied to the circulation tank 24 through the circulation channel. A pump 23 for circulation (circulation) is provided.

  In the present invention, the ice making water storage tank 1 capable of storing ice making water to be supplied to the circulation tank 24 is not connected to a water pipe or the like as in the prior art (that is, independent). The ice making device 89 is provided.

  Moreover, in the ice making device 89 of the present invention, when the ice making water stored in the circulation tank 24 becomes drainage (for example, when uniced water is discarded at regular intervals to generate highly transparent ice), The drainage water storage tank 2 configured to store the wastewater may be provided without being connected to a drain pipe or the like (that is, independent) as in the related art.

  In short, it is sufficient that at least one of the ice making water storage tank 1 and the drainage water storing tank 2 is provided in the ice making device 89 independently.

  With such an ice making device 89 of the present invention, for example, a tap water can be easily supplied to a long distance using a small hose, but a drain hose must use a large hose. In such an environment, only the drainage water storage tank 2 is attached to the ice making device 89, while the tap water can be used as ice making water through the water supply port, for example, without providing the ice making water storage tank 1. That is, even in a place where there is no drain pipe or the like, the ice making device 89 of the present invention can be moved and installed and used.

  In addition, in order to improve the quality of ice, it is often desired to use purified water, but the quality of the wastewater itself is not particular. In such a case, with the ice making device 89 of the present invention, only the ice making water storage tank 1 can be attached to and detached from the ice making device 89, while the drainage water storage tank 2 is not provided, and the water is not connected to the ice making device 89. It is also possible to dispose of frozen water or the like into a drain pipe.

  That is, even in a place where a water pipe or the like does not exist, the ice making device 89 of the present invention can be moved and installed and used. Therefore, the ice making device 89 of the present invention can reduce the restriction of the installation location.

[Embodiment 2]
A second embodiment of the present invention will be described. In addition, about the member which has the same function as the member used in Embodiment 1, the same code | symbol is attached and the description is abbreviate | omitted.

  In the first embodiment, the ice generation process and the like in the ice making device 89 provided with the detachable ice making water storage tank 1 and the drainage water storing tank 2 have been described. By the way, in the ice making device 89 of the present invention, various sensors (that is, sensor groups) are attached. Therefore, in the ice production process, for example, the following control can be performed using these sensors.

[1. (Stop of ice making operation in ice making process)
<1-1. In case of insufficient water storage in ice making water storage tank>
In the ice making process, there may be a case where a predetermined amount of ice making water in the ice making water storage tank 1 is not stored due to evaporation of ice making water, forgetting to replenish ice making water storage tank 1 or the like. In such a case, if the cold gas cycle is operated or the pump 23 is driven even though the ice making water is insufficient, the power consumption of the ice making device 89 is wasted.

  Therefore, in the ice making device 89 of the present invention, the ice making water storage amount detection sensor 52 for detecting the amount of water stored in the ice making water storage tank 1 and the control unit 71 for controlling whether or not the ice tray 25 is cooled are provided. The control unit 71 stores a predetermined threshold ice-making water weight, compares the threshold ice-making water weight with the detection result of the ice-making water storage amount detection sensor 52, and according to the comparison result. Whether or not the ice tray 25 is cooled is controlled.

  More specifically, in the ice making device 89 of the present invention, when the weight detected by the ice making water storage amount detection sensor 52 comprising a weight sensor is lighter than the threshold ice making water weight, the control unit 71 determines that the ice making water is ice making water. It is determined that a predetermined amount is not stored in the water storage tank 1. The control unit 71 that has made such a determination immediately stops the driving of the cold gas cycle (ice making operation) in the refrigeration cycle unit 19 and the driving of the pump 23. . As a result, the ice making device 89 of the present invention can eliminate waste of power consumption.

  In addition, after stopping the driving of the cold gas cycle and the driving of the pump 23 (stopping the ice making operation) in this way, the control unit 71 stores the ice that has already been generated in a good quality state. The inside of the ice storage 27 may be kept cold (the cold keeping operation may be started).

  In addition, this cool keeping operation means that the controller 71 stops the driving of the pump 23 to stop the blowing of ice making water to the ice tray 25, and the cool air generated in the evaporator 15 causes the inside of the ice storage 27 to be stopped. It is an operation that controls the temperature.

<1-2. When the ice in the ice storage exceeds the allowable storage capacity of the ice storage>
As the continuous ice making process and deicing process are repeated, the generated ice gradually accumulates in the ice storage 27. However, since the ice storage 27 has an allowable storage amount, an infinite amount of ice cannot be stored. Then, in the ice storage 27, although the ice making process and the de-icing process are repeated even though the ice cannot be stored (despite being full ice), the generated ice is stored in the ice storage. 27, which may lead to damage to the ice making device 89 itself.

  Therefore, the ice making device 89 of the present invention is provided with an ice storage amount detection sensor 55 for detecting the ice storage amount in the ice storage 27 and a control unit 71 for controlling whether or not the ice tray 25 is cooled. The control unit 71 stores a predetermined threshold ice storage weight, compares the threshold ice storage weight with a detection result of the ice storage amount detection sensor in the ice storage, and according to the comparison result, an ice tray. Whether or not 25 is cooled is controlled.

  Specifically, in the ice making device 89 of the present invention, when the detected weight detected by the ice storage amount detection sensor 55 in the ice storage comprising the weight sensor is heavier than the threshold ice storage weight, the control unit 71 stores the ice in the ice storage device. It is determined that there is a high possibility that the allowable storage amount in the storage 27 will be exceeded. The controller 71 that has made such a determination immediately causes the refrigeration cycle unit 19 to stop driving the cold gas cycle and stop driving the pump 23. As a result, a situation where the ice making device 89 of the present invention is damaged can be prevented.

  As described above, after the cold gas cycle drive stop / pump 23 drive stop is performed, the control unit 71 may cause the ice making device 89 to start the cold insulation operation.

<1-3. When the drainage volume of the drainage storage tank exceeds the allowable storage volume>
Further, as the continuous ice making process and deicing process are repeated, the amount of wastewater stored in the wastewater storage tank 2 naturally increases. However, since the drainage water storage tank 2 has an allowable water storage amount, an infinite amount of wastewater cannot be stored. Then, in the drainage water storage tank 2, the wastewater is discharged from the drainage water storage tank 2 when the ice making process and the deicing process are repeated, even though the wastewater cannot be stored (although it is full). Overflow (water leaks) may eventually lead to damage to the ice making device 89 itself.

  Therefore, in the ice making device 79 of the present invention, a waste water storage amount detection sensor 53 that detects the amount of waste water stored in the waste water storage tank 2 and a control unit 71 that controls whether or not the ice tray 25 is cooled are provided. . The control unit 71 stores a predetermined threshold drainage weight, compares the threshold drainage weight with the detection result of the drainage water storage amount detection sensor 53, and determines the ice tray 25 according to the comparison result. Whether or not to cool is controlled.

  Specifically, in the ice making device 89 of the present invention, when the detected weight detected by the ice storage amount detection sensor 55 in the ice storage comprising the weight sensor is heavier than the threshold drainage weight, the control unit 71 sets the drainage storage tank. It is judged that the possibility of exceeding the allowable water storage capacity in 2 is high. The controller 71 that has made such a determination immediately causes the refrigeration cycle unit 19 to stop driving the cold gas cycle and stop driving the pump 23.

  As described above, after the cold gas cycle drive stop / pump 23 drive stop is performed, the control unit 71 causes the ice making device 89 to start the cold insulation operation.

[2. (Stopping water supply to the circulation tank, etc.)
In the above description, the stop of the ice making operation for preventing the case where the drainage water leaks from the drainage water storage tank 2 has been described mainly because the continuous ice making process and the deicing process are repeated.

  However, as another factor, the ice stored in the ice storage 27 melts for some reason (for example, temperature rise caused by inflow of outside air due to frequent opening and closing of the door), and this melted water is stored in the drainage water storage. In some cases, the tank 2 gradually accumulates. That is, the temperature in the ice storage 27 rises for some reason, and ice may melt excessively, and the melted water may cause water leakage from the drainage water storage tank 2.

  In order to prevent such a water leakage state, the ice making device 89 of the present invention uses the ice storage temperature detection sensor 54 and the ice storage amount detection sensor 55 in the ice storage.

  For example, it may be determined from the temperature detected by the ice storage temperature detection sensor 54 that the inside of the ice storage 27 is higher than room temperature or the like, and the weight detected by the ice storage amount detection sensor 55 in the ice storage tends to gradually decrease. In such a case, the control unit 71 determines that the ice in the ice storage 27 has melted and the amount of water stored in the drainage water storage tank 2 has increased due to the melted water.

  In this case, the control unit 71 first melts the ice stored (stocked) in the ice storage 27 by lowering the temperature in the ice storage 27 (by performing a cold insulation operation). Is to prevent. Then, in order to prevent the inflow of unfrozen water into the drainage storage tank 2 generated by the repetition of the ice making process and the deicing process, the control unit 71 performs ice making water from the ice making water storage tank 1 to the circulation tank 24 in the ice making process. Is stopped (step S7 in FIG. 4 is stopped).

  In this way, if the temperature in the ice storage 27 is first lowered and the flow of ice-making water into the circulation tank 24 is stopped, the amount of water stored in the drainage water storage tank 2 is increased by the dissolved water in the ice storage 27. Since it is determined that the dissolved water has flown, further inflow of the dissolved water into the drainage water storage tank 2 can be prevented. Therefore, leakage of the drainage water storage tank 2 due to the dissolved water can be prevented.

  In the above description, the case where the ice storage temperature detection sensor 54 and the ice storage amount detection sensor 55 are used has been described. However, the ice storage temperature detection sensor 54, the ice storage amount detection sensor 55, and the drainage are stored. The stored water amount detection sensor 53 may be used.

  For example, it can be determined from the temperature detected by the ice storage temperature sensor 54 that the inside of the ice storage 27 is higher than room temperature, etc., and the weight detected by the ice storage amount detection sensor 55 in the ice storage tends to gradually decrease. There is a case where the weight detected by the storage amount detection sensor 53 tends to increase rapidly.

  In such a case, as described above, the control unit 71 is higher if the ice in the ice storage 27 is melted and it is determined that the amount of water stored in the drainage storage tank 2 is increased by the melted water. It is possible to prevent water leakage from the waste water storage tank 2 with accuracy.

[Embodiment 3]
Embodiment 3 of the present invention will be described. In addition, about the member which has the same function as the member used in Embodiment 1 * 2, the same code | symbol is attached and the description is abbreviate | omitted.

  As shown in the first embodiment, when the detachable drainage water storage tank 2 is provided, the drainage water storage tank 2 is removed from the ice making device 89 in order to prevent leakage from the drainage water storage tank 2, and the contents are stored. The wastewater needs to be discarded. Therefore, in the third embodiment, in order to reduce the number of times the wastewater in the wastewater storage tank 2 is discarded (so that the wastewater in the wastewater storage tank 2 does not need to be frequently discarded), A means for evaporating a part or all of it will be described.

[1. (Changing the position of the condenser etc.)
As an example of evaporating the wastewater stored in the wastewater storage tank 2, there is an ice making device 89 as shown in FIG. In this ice making device 89, the condenser 12 is disposed on the open surface of the drainage water storage tank 2, the exhaust opening 42 is disposed in the casing 41 located on the bottom surface side of the drainage water storage tank 2, The air cooling fan 13 is disposed at a position where the driving heat of the condenser 12 can be blown to the open surface of the drainage water storage tank 2 (for example, at a position where the condenser 12 can be sandwiched between the drainage water storage tank 2). An air cooling fan 13 is provided).

  If it is such arrangement | positioning relationship, while the air-cooling fan 13 rotated, the drive heat (drive heat at the time of a cold gas cycle) of the condenser 12 was cooled, and it was heated resulting from this drive heat. Air (warm air) is blown to the open surface of the drainage water storage tank 2. Then, the waste water stored in the waste water storage tank 2 evaporates, and there is no need to discard the waste water in the waste water storage tank 2 for a long time (long term).

  That is, in the present invention, the wastewater stored in the drainage water storage tank 2 is gradually evaporated so that the amount of drainage does not reach the allowable water storage amount of the drainage water storage tank 2. As a result, the ice making device 89 is capable of making ice for a long time without discarding the wastewater in the drainage water storage tank 2 (the ice making device 89 having a reduced number of wastewater disposal in the drainage water storage tank 2 and )

  The warm air reaches the drainage water storage tank 2 and is then discharged to the outside of the machine (outside the ice making device 89) through the exhaust opening 42. For this reason, it is possible to prevent a situation in which the hot air itself stays in the ice making device 89. Further, by blowing warm air to the open surface of the drainage water storage tank 2 by the air cooling fan 13, the evaporation of the wastewater is further promoted.

[2. (Installation of small condenser)
<2-1. Installation of small condenser only>
Another example of evaporating the wastewater stored in the wastewater storage tank 2 is an ice making device 89 provided with a small condenser 3 as shown in FIG. The small condenser 3 is provided in the refrigerant pipe 18 from the compressor 11 to the condenser 12 (large condenser 12) so as to condense the refrigerant in the previous stage flowing into the large condenser 12. It has become. That is, the small condenser 3 is a condenser 12 that performs pre-processing before the large condenser 12 condenses the refrigerant compressed by the compressor 11.

  As with the large condenser 12, the small condenser 3 also emits heat when it is driven (to generate driving heat). Therefore, in the ice making device 89 of FIG. 6, the waste water stored in the waste water storage tank 2 is evaporated using the driving heat of the small condenser 3.

  Therefore, the small condenser 3 is provided on the bottom surface side of the drainage water storage tank 2. When the small condenser 3 is disposed at such a position, the driving heat is easily conducted to the drainage water storage tank 2 and the stored wastewater can be efficiently evaporated. In addition, in order to improve the adhesiveness to the bottom face of the drainage water storage tank 2, the small condenser 3 is preferably in a plate shape.

<2-2. Installation close to small and large condensers>
Further, in the ice making device 89 of the present invention, the waste water in the waste water storage tank 2 may be evaporated using the drive heat of both the small condenser 3 and the large condenser 12.

  For example, in the ice making device 89 of the present invention shown in FIG. 7, the small condenser 3 is arranged on the bottom surface side of the drainage water storage tank 2 as in the ice making device 89 shown in FIG. Further, in this ice making device 89, the large condenser 12 is disposed on the open surface of the drainage water storage tank 2, and the exhaust opening 42 is disposed in the casing 41 located on the bottom side of the drainage water storage tank 2. In addition, the air cooling fan 13 is arranged at a position where the driving heat of the large condenser 12 can be blown to the open surface of the drainage water storage tank 2.

  That is, in the ice making device 89 of the present invention shown in FIG. 7, the large condenser 12 is disposed on the open surface side of the drainage water storage tank 2 and the small condenser 3 is disposed on the bottom surface side of the drainage water storage tank 2 (large size). By arranging the condenser 12 and the small condenser 3 in the vicinity, both the driving heat (warm air caused by the driving heat of the large condenser 12 and the heating caused by the driving heat of the small condenser 3) and the drainage water storage The waste water in the tank 2 is evaporated. As a result, the waste water in the waste water storage tank 2 can be evaporated more efficiently than the ice making device 89 of FIG.

  As described above, the hot air resulting from the drive heat reaches the drainage water storage tank 2 and is then discharged to the outside of the apparatus (outside of the ice making device 89) through the exhaust opening 42. 13, the warm air is blown to the open surface of the drainage water storage tank 2, thereby further promoting the evaporation of the wastewater.

  Moreover, if the waste water in the waste water storage tank 2 is evaporated as in the third embodiment, it is taken as a countermeasure when the waste water amount in the waste water storage tank 2 described in the second embodiment exceeds the allowable water storage amount. In other words, the ice making operation is not stopped in the ice making process, or the cold insulation operation is not performed. As a result, the ice making process and the deicing process can be performed continuously.
